I've noticed that payment with paypal can be done even if the T&C box is not accepted and in the config is required. While Offline pay correctly become impossible without accepting T&C, paypal payment can be done. if T&C is selected, then deselected then it works, but initially T&C aren't a problem for paypal.
It would be nice even if the customer get a notice when trying to buy without accepting T&C (otherwise he can be confused why isn't working).
Thanks and regards,
